I ANTIGLARE ATTACHMENT FOR HEADLIGH'I'S Filed Jam. '25. 1930 3 Sheets-Sheet a Inventor Patented May 19,' 1931 PATENT OFFICE HANS PETER VEB-DICH, F ABERDEEN, SOUTH DAKOTA .A NTIGLARE ATTACHMENT FOR HEADLIGHTS Application filed January 28, 1930. Serial No. 422,873.

The present invention relates to attachanents for headlights of motor vehicles and has for its primary object to provide an anti glare attachment so as to eliminate glare from the eyes of the driver of an approaching vehicle or pedestrian, but which affords ample illumination of the road while driving in the dark.

A further object is to provide an attachment of this character which may be installed in position upon a conventional type of headlight casing without necessitating any changes in the construction or alterations thereof. Another object is to provide an attachment of the above mentioned character which is simple and practical in construction, efficient and reliable in performance, relatively inexpensive to manufacture and install in operative position and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction, combination and arrangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accon'ipanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of a headlight casing with parts broken away and shown in section to illustrate the position of the anti-glare attachment when placed inwardly of the lens,

Figure 2 is an elevational view of the antiglare attachment, 7

Figure 3 is a fragmentary sectional view taken along a line 3-3 of Figure 2,

Figure 4 is a side elevational view of a modified form of headlight casing, with parts broken away and shown in section,

Figure 5 is a front elevational view of the form of the invention illustrated in Figure 4, Figure 6 is a fragmentary vertical sec tional view through the lens of a headlight showing the invention in the form of a shield, Figure 7 is a front elevational view of the shield, I Figure 8 is a rear elevational view thereof,

Figure 9 is an elevational view of a modificd form of the invention, and Figure 1.0 is a plan view of a further modification of the anti-glare material.

Referring to the drawings in detail, and more particularly to the form of the invention illustrated in Figures 1 to 3 inclusive. for the purpose of illustration I have disclosed the invention shown in use upon a conventional type of headlight casing 5 having a lens 6, which may be in convex form as shown in Figure 1, or provided with plain surfaces and secured in position to the forward edge of the casing by the usual annuv lar ring member 7. 5

The anti-glare. attachment indicated generally at 8 is placed'inwardly of the lens and comprises an annular ring 9, preferably constructed of composition and compressed to provide the desired degree of rigidity so that the ring will serve to support the antiglare material 10 which extends across the ring and secured at its edges to the ring by suitable fastening means 11. The anti-glare material is preferably what is commonly known as cello glass, but of course can consist of any suitable material adapted to produce the desired diffusion of the rays of light passing through the lens.

The anti-glare material may be cut into any desired shape or form, either as a cross as shown in Figure 2, or as a panel as shown in Figure 9, or as a star as shown in Figure 10, or if preferred may cover the entire upper 4 half of the ring as shown at 14 in Figure 8. 55

In the form of the invention shown in Figure 1 an outer ring member 15 is also socured to the ring member 9 with the antiglare material interposed therebetween thc inner peripheral edge of the outer ring member 15 being formed into a lip 16 for overlapping the edge of the lens 6 to assist in retaining the lens in position.

The invention as shown in connection with a modified form of headlight casing in Figures and 5, wherein the casing is provided with a frusto-c-onical or spherical member 17 having its central part open within which a relatively small lens 18 is secured. 100

The anti-glare attachment 19 is placed rearwardly of the lens and is also secured to the edge of the member 17 In Fi res 6 and 7 the invention is shown in the orm of a shield 20 extending outwardly over the upper portion of the lens 6, the edges of the shield being secured between a pair of the composition ringmembers 21 by fasteners 22. The inner peripheral edges of the ring members 21 overlie I the edges of the lens so as to secure the lens in position, the lens being prevented from inward movement by a retaining ring 23 and all of the ring members are secured in assembled position to the casing by the casing I'lIl 1% the modification shown in Figure 10 of the drawings, the star shaped anti-glare shield is adapted to be secured in position like the shields of Figures 1 to 3, inclusive, and 4, 5 and 9, to break up the glare of the headlight and properly diifuse the light produced thereby.

It will be apparent from the foregoing that the anti-glare attachment constructed in accordance with my invention may be easily and quickly mounted in position upon the headlight casing and will serve to properly diffuse the rays of light from the headlight so as to prevent the blinding of the drivers of oncoming vehicles or pedestrians.

It is obvious that my invention is susceptible to various changes and modifications in construction without departing from the spirit of the invention or the scope of the appended claim.

Having thus described my invention, What I claim as new is:

A dimmer attachment of the type described for positioning behind the lens of a vehicle headlight comprising an annulus positioned in contact with said lens at the marginal portion thereof, and an non-circular sheet of ii ht difl'using material secured at its outer edge to said annulus, said annulus being further ositioned between the casing of the headligli t and said lens, and a second annulus secured to the said annulus and being deformed to overlie the front marginal portion of the lens for retaining the same,

said lens and annuli being mounted on the headlight casing by an annular lens mounting ring member.

In testimon whereof I aiiix my signature.

ANS PETER VERDICH.
